ios - 在没有用户交互的情况下以编程方式拍照

Question

如何在没有用户交互或不显示 ImagePickerController 的情况下拍照

  UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {
        [imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
    }

    // image picker needs a delegate,
    [imagePickerController setDelegate:self];

    // Place image picker on the screen
    [self presentModalViewController:imagePickerController animated:YES];

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissModalViewControllerAnimated:YES];
    _myImageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

我知道这样我可以自动拍照 我如何完成？

Answer 1

您可以使用 takePicture UIImagePickerController 上的方法以编程方式拍照。

但我建议使用AVFoundation为您创建 onw 图像捕获。
